47. A seven-year-old in-foal mare, left in hospital r8th February, 

 1897. 



About six weeks before the animal had been bled from the left 

 jugular. Phlebitis resulted, and was treated by laying open the parts 

 and cleansing with disinfectant lotions. Recovery appeared to be 

 taking place when the parotid region became inflamed. 



On examining the animal on the nth February we discovered a 

 subparotid abscess developed between the middle and upper thirds of 

 the gland. It was punctured and washed out with 30 per cent, iodine 

 solution. The condition becoming aggravated, the animal was left in 

 hospital on the i8th February. 



State on Entry. — The entire left parotid region was greatly swollen 

 and very painful. The swelling extended from the wound in the vein 

 to the temporo-maxillary region and back of the neck, passing round 

 the base of the ear. The subparotid abscess communicated with the 

 wound in the vein. The animal discharged from the left nostril. It 

 .refused part of its food. 



Treatment. — Drainage of the vein and injection of the sinus with 

 30 per cent, solution of iodine and iodide of potassium. 



On the igth February two small abscesses had developed above 

 the first, and were opened. They contained little pus. 



On the 22nd two more abscesses were opened ; one, of considerable 

 size, had developed behind the parotid, the other near the base of the 

 ear. The cavities were cleansed, and the sinus irrigated with iodine 

 solution. A fragment of the gland tissue was removed. When feeding 

 saliva escaped by the parotid wounds. 



On the 25th a deep-seated abscess opened in the pharynx, and pus 

 escaped by the nostrils. 



On the 28th another parotid abscess was opened, and a counter- 

 opening made in Mborg's triangle. 



From this time onwards improvement was steady. 



On the 17th March drainage of the vein was stopped. 



A week later the wounds had healed. The parotid region and 

 upper part of the jugular furrow remained slightly swollen, but the 

 swelling soon afterwards disappeared. 



48. Six-year-old mare, left in hospital on the nth January, 1897. 

 A month before the animal had suffered from strangles, and had 



been bled from the left jugular. 



The patient was brought in an ambulance, and was so thin and 

 feeble as to require support when walking. Scarcely any weight was 

 borne on the near hind limb. On being placed in a box it soon fell 

 into a comatose state, remaining quite still, the eyes half closed, the 

 head depressed, the limbs brought together under the body ; from time 

 to time the animal was obliged to lean for support against the wall. 



The mouth was hot and dr}- ; the conjunctiva yellowish in colour ; 

 the pulse 80, small and thready ; respirations 22 ; temperature 39"5° C. 



The hair had been removed from the left parotid region b}' the 

 action of vesicants. In the upper part of the jugular furrow was a 

 warm, slightly painful swelling, extending over the parotid, and show-
